A microbial test is a laboratory test that checks for the presence of microorganisms in a sample provided to the laboratory. While this is correct, the inoculation definition for microbiology is more specific to introducing microorganisms into environments where they will grow and thrive. A urine culture is a test that can detect bacteria in your urine. How to use microbiology in a sentence. Subject. The specificity of a test is expressed as the probability (as a percentage) that a test returns a negative result given that that patient does not have the disease. Clinical Microbiology. Definition and Measurement. MR-VP broth is used for both MR Test and VP test. The qualitative phase of a microbial limits test is known as the Test for Specified Microorganisms. The MPN method is used to quantify the concentration of the viable microorganisms in a sample and involves inoculating decimal dilutions into tubes of a broth medium, observing results and using a standard MPN table. Motility Test – Principle, Procedure, Uses and Interpretation Last updated: June 14, 2019 by Sagar Aryal Motility is the ability of an organism to move by itself by means of propeller-like flagella unique to bacteria or by special fibrils that produce a gliding form of motility. The most probable number (MPN) is the number of organisms that are most likely to have produced laboratory results in a particular test.
